Fertilize azaleas as they finish blooming. Because they have shallow root systems, they appreciate several light applications of fertilizer during the growing season rather than one large dose. For best results, use one of the special blends of azalea fertilizers and apply according to label directions.
Refurbish Raspberry Plants
Cut out all the dead canes from your raspberry patch. The new canes that will bear this year's fruit should have new, swollen buds along the edges. Thin these to five canes per foot of row to allow good air circulation and prevent overcrowding.
Rake and Renew Flowerbeds
Start renewing mulch around flower beds and trees. Incorporate decaying mulch into the soil, fluff up existing mulch, and refresh it by adding a thin layer of new material. Add three inches or so of mulch to areas that have not been previously mulched. Take care to keep mulch away from direct contact with your plants.
Plan for More Color
To extend the blooming period of gladiolus, plant early-season, mid-season, and late-season selections each week until the middle of June. Choose a sunny location and plant the corms 4 to 6 inches deep and 6 to 8 inches apart.
Pick Up Yard Debris
Remove sticks, rocks, and other debris from your lawn to prevent damaging your lawn mower or injuring yourself when mowing. Check your lawn mower and other lawn care equipment in preparation for the coming season.
